METHOD AND MECHANISM FOR REMOVING CENTBIFUGE EFFLUENTS.

Griginal application led October 7, 1921, 'Serial No. 506,165. Divided and this application led April 9,

19727.YA Serial No. 182,236.` A

The method and mechanism of this in-`A vention are designed to facilitate the re-l moval of viscous orv other eiuents discharged from centrifugal rotors and disposed to adhere to receivers therefor,thus accumulating and interfering with the desired operations.

The invention is characterized by the discharge of a Huid within the 'receptacle into which an eiiiuent from a centrifugal rotor is received and so aecting said effluent as to prevent its accumulating in the receptacle.`

In the treatment of petroleum oil for the separation therefrom of petrolatum or wax contained therein, the oil has been chilled and then run through a centrifugal rotor from which the separated waxVY and wax freed oil are delivered to receiving compart- Y. ments or covers; a carrier liquid, such as brine, being used in the rotor for facilitating the operation.

As the wax discharged from the bowl is viscous, it is disposed to adhere to the walls of the compartment orcover into which it is discharged and to accumulate, with resulting obstruction of the operation after some time.

In the preferred practice of my invention, hot brine is delivered against the top of the compartment for receiving the wax effluent and washes such top so as to heat the same and removethe wax therefrom, the wax being heated by the heated surface against which it is thrown, by contact with the brine and by the heated atmosphere of the compartment. so that its iuidity is increased and its discharge from the cover or receptacle is facilitatedf The invention is comprised in the construction and operation set out in the following description and the accompanying drawings in illustration thereof.

In the drawings. Fig. 1 is a broken sectional view showing the top of a centrifugal rotor provided with improvements of my invention, and Fig. 2 is a part sectional plan of the construction as seen with the top cover removed.

In the drawings, the` centrifugal rotor 1 has the neck 2, by which it is suspended and revolved, andpis provided with the assages 3 and 4f, through which the centrifugally separated and stratified constituents are discharged.

In the separation of wax from chilled oil, the separated waxy iiows through the passages 3 to the channel 5 whence it is discharged over the weir or dam 6 concentric l with the rotor, andthe Wax freed oil Hows to the discharge passages 4ever the weir or dam 7 and through the compartment 8 concentric with the rotor.

A cover 9, supported detachably by the case 10, providesthe compartment 11 into which the wax is'l discharged as it is delivered over the Weir 6, and a cover 12, supported detachably by the cover 9, provides a compartment 13 for receiving the wax freed oil from the passage or passages 4.

A tubular ring or delivery conduit 14, connected with a supply conduit 15 and provided with the apertures v14', encircles the bowl neck y2 in proximity to the top of the bottom surface of the conical bottom 12 of the cover 12, the part 12 forming the top of the compartment 11. The conduit 14 is adapted for discharging hot fiuid through its peripheral openings 14 against the bottom surface of the part 12 above the wax discharged over the Weir 6, such wax in greater or less amount being thrown against the part 12. As the heating fluid or hot brine, which is fed through the conduit 15 to the conduit 14 and discharged through the openings 14 thereof, washes the bottom surface of the part 12', heats the compartment 11, heats the wax and acts directly upon the wax, the latter is thus caused to flow freely from the compartment 11 through the spout 11 thereof.

From the foregoing it will be apparent that hot uid projected against the common wall dividing compartment 11 from cornpartment 13will heat that common wall 12', and also the atmosphere within compartment 11, and the heatof that common Wall 12 will heat the atmosphere in 'compartments l1 and 13.

This application constitutes a division of mycopending application Ser. No. 506,165, filed October 7, 1921, in which the broad aspect of my invention is claimed wherein the condition of a substance discharged in dispersed form from a 'centrifugal machine in which the substance was subjected to centrifugal treatment, is controlled by regulating the condition of the atmosphere Within' which the substance is so discharged; the claims of said application also covering that species of my invention wherein the condition of the substance so discharged is controlled by .regulating the temperature of the atmosphere within which the substance exists in dispersed state.

1What li claim as new and desire to secure by Letters Patent of the United States is:

1. The method of separating wax from petroleum which comprises chilling the wax` the Wax from the oil and discharging the separated wax from the influence of centrifugal force against the wall of a collecting receptacle While discharging a jet of hot 'iuid against said wall and thereby heating the Wax to facilitate further removal of the wax.

3. The method of separating wax from petroleum which comprises chilling the wax earing oil to such temperature as Will precipitate the wax, centrifugally separating the wax from the oil and separately discharging the separated wax against a partition While projecting hot fluid against the surface of the partition impinged by the wax and flowing 'the wax-freed oil Vover the opposite surface of said partition.

4f. In centrifugal apparatus for the separation of wax from petroleum of a centrifugal bowl having routlets respectively for the discharge of wax and wax-freed oil, re-

ceptacles respectively positioned to receive o1l and wax discharged from said outlets,

and means heating the interior of the oil receiving receptacle.

5.` lin centrifugal apparatus foi' the separation of Wax from petroleum, the combination `of a centrifugal bowl having outlets respectively for the d-ischarge of wax and Wax-freed oil, receptacles provided with spouts and respectively positioned to receive oil and wax discharged from said outlets, and means heating the interior of the oil receiving receptacle and the wax and washing wax toward the spout of its receptacle.

i. The method which consistsI in centrifugally separating wax from petroleum oil, separately discharging the separated wax and wa'x freed oil, and bringing brine at a temperature to melt the wax into contact with the discharging wax. l

The process of separating wax from petroleum oil, which comprises reducing the oil containing wax in solution to a temperature sufficiently' low to throw the'wax out of solution, separating the wax from the oil by vcentrifugal force, separately discharging the separated wax and oil out of the influence of the centrifugal force and subjecting the separated wax as it is so discharged and passed from the influence of centrifugal force to heat to render it more free flowing, and then flowing away the heated Wax.

8. The process of separating wax froln petroleum oil, which comprises reducing the solution to a temperature sufficiently low to throw the wax out of solution, separating the wax from the oil by centrifugal force, subjecting the discharging separating wax to heat to render it more free flowing, and flowing away the heated wax.

9. The method of separating wax from petroleum which comprises chilling the waxbearing oil to such temperature as will precipitate the wax, centrifugally separating the wax from the oil and separately discharging the wax and wax-freed oil from the influence of centrifugal force, and discharging hot liquid into contact with the separated wax as it. is so discharged and passed from the influence of centrifugal force to heat the waxand thereby heating the wax to render it more free flowing and washing the wax away.

1U. The method of-scparating wax from petroleum which comprises chilling the waxbearing oil lo such temperature as wilt precipitate the wax, centrifugally separating the wax from the oil and separately discharging the wax against the wall of a colllccting receptacle, and discharging liquid against said wall and thereby washing the discharged wax toward an outlet of said receptacle.

ln testimony whereof, ll have signed my name to this specification.
